Discrete event simulation

From Wikipedia, the free encyclopedia

In discrete event simulation, the operation of a system is represented as a chronological sequence of events. Each event occurs at an instant in time and marks a change of state in the system [1]. For example, an event could be "lift at level 2" or "level 6 button pressed".

A number of mechanisms have been proposed for carrying out discrete event simulation, among them are the event-based, activity-based, process-based and three-phase approaches. The three-phase approach is used by a number of commercial simulation software packages, but from the user's point of view, the specifics of the underlying simulation method are generally hidden.
